Unabiker 06-09 YZ450F rad guards feature extensive use of support rods to provide complete protection for your rads. This system of rods makes it virtually impossible to squash your rads. We use 2 support rods across the front of the rad, 3 rods across the back of the rad, and 2 rods connecting the left and right guards to increase fold-back resistance. Our guards also feature a large slot on the side of the guard to allow high pressure air to flow off the rad shroud and across the face of the rad. This provides maximum cooling, while your rads receive maximum protection. Unabiker 06-09 YZ450F rad guards are available in bare aluminum
